Although, boron (B) is an essential micronutrient for plants, animals and human beings; at high concentration of boron in water resources may be hazardous for living being. Hence the boron concentration has to be reduced down to suggested level by the World Health Organization for safe use of water for irrigation and drinking. The present study examines boron pollution level in groundwater and suggests an alternative sorbent to remove it from water sources used for irrigation and drinking. The poly-2-Hydroxyethyl methacrylate (HEMA)-co-glycidyl methacrylate (GMA)-polyethyleneimine (PEI)-Fe 3+ columns were synthesized to adsorb the boron compounds from a real groundwater samples and synthetic solution. Boron was removed 78.2% by poly (HEMA-co-GMA)-PEI-Fe 3+ column at an amount of 54.42 mg/g, pH 8. However, the lower adsorption ratio was recorded as between 35.8-58.1% of real groundwater where adsorbed amount of boron and its derivates were found as 9-28.67 mg/g due to other chemical ions in real groundwater samples. Boron-loaded columns were regenerated by 0.01 M NaOH treatment for industrial practice. Regeneration cycles were performed successfully 15-times with only a loss of 5% in adsorption capacity of columns.

“…With the development of industry, the acceleration of urbanization, and the increase of agricultural chemicals using, soil pollution problems have become increasingly prominent and attract more and more attention worldwide in recent decades (Zhao et al 2020;Kumar et al 2019;Zhang et al 2019;Akopyan et al 2018;Yang et al 2018;Li et al 2017 ). Among all kinds of soil pollutants, heavy metal(loid)s cause more attention due to their high toxicity and non-biodegradability (Wu et al 2020).…”

Risk and source of heavy metal(loid)s (As, Cu, Cr, Pb, Mn, Ni, V, and Zn) were determined in the surrounding farmland soil of a zinc smelter in the water source area of the Mid-route of South-North Water Transfer Project of China to explore the impact of smelting activity on local environment. The heavy metal(loid)s contents were analyzed by X-ray uorescence spectrometry and their pollution levels and ecological risks were assessed by geoaccumulation index, Nemerow synthetic pollution index and potential ecological risk index. The possible sources of the heavy metals(loid)s were identi ed by multivariate statistical analysis methods. The mean contents of the heavy metal(loid)s in the farmland soil were above the local soil background values except Mn. The contents of As, Cu, Pb, Zn, and Ni in the downwind direction soil decreased with the distance increasing between the sampling site and the zinc smelter. The investigated soils were moderately to seriously polluted by heavy metal(loid)s and the heavy metal(loid)s presented moderately ecological risk as a whole. As, Cu, Pb, and Zn mainly originated from zinc smelting activities. Cr, Mn, and V primarily derived from natural source. Ni mainly came from zinc smelting activities, partly from natural source. The zinc-smelting activity in uenced the heavy metal(loid)s content, particularly Zn and Pb, in the surrounding farmland soil. The local government should strengthen the cooperative monitoring of heavy metal(loid)s in farmland and agricultural products, as well as pollutant emission monitoring and control.

“…To address shortage in water resource and uneven distribution of water resources, water-saving measures are necessary to improve usage efficiency of water resource, such as dams and reservoirs, drip irrigation, water channel anti-seepage and other techniques 11 . These water conservation measures are typically used in local areas, and especially in arid and semi-arid areas, where human intervention has a greater impact on land water fluxes 12 . Remote sensing has been widely applied to many studies to analyze the changes of land use and cover and the inter-annual variation of landscape pattern, to assess the ecological security and ecological effect, and to conduct researches about the driving mechanism of such changes 13–24 .…”

Widespread application of water-saving measures, especially advanced drip irrigation technologies, may significantly impact on the land use, and further potentially alter regional ecological environments in an arid area. In this study, the remote sensing and geographic information system technology were used to analyze the LANDSAT images (1976–2015) and the MOD16 evapotranspiration data (2000–2015) in the Manas River Basin (MRB), China where the water-saving technologies have experienced the past 40 years. Our results show that the area of the cultivated land was approximately doubled from 1976 to 2015 with a dynamic degree of cultivated land ranging from 1.7% to 4%. The reclamation rates were estimated at 9.5% in 1976 and 21.8% in 2015 and the comprehensive index of land use degree shows an increasing trend in the MRB. The evapotranspiration in the MRB suggests that the cultivated land is becoming more humid while the other regions are becoming more arid. Long-term change in the land use is mainly promoted due to the multiple years’ efforts on development of the water-saving technologies. This study greatly improves our understanding of the interactions between change in ecological environments and human activities and may provide policy makers guidance of sustainable development at an arid area.
